In fact, CNN just reported on a survey from AAA that showed a full one-in-five Americans saying they are likely to buy an electric car for their next new vehicle. True, as CNN points out, answering a survey and buying a car are two different things. But as awareness grows, vehicle choices expand, and charging options proliferate, I do expect to see non-linear growth in demand for plug-in vehicles.

After all, I'm still regularly meeting genuinely environmentally conscious people who do drive cars, and who have little to no idea of what electric and plug-in options are available to them. Once I start telling them about the costs of electric driving, and the range of vehicles that are beginning to become available, I see their interest grow. In other words, I suspect there's a much larger market below the surface than anyone really realizes.
